So I got to go to a mini-festival at a covered market in Okayama, and while I didn't get to do the goldfish game, I played its cousin, a much easier game involving rubber balls (including a 4 star Dragonball)
It was kind of fun. https://www.youtube.com/watch?v=jGOVIa1qx5w
There are events going on in the covered markets on a lot of weekends, so I'm sure I'll have more to show. The Town's claim to fame is Momotaro (Peach boy), so I'm sure there's a Momotaro festival at some point which I hope to see.
